FmcDIO5chTTLa is a 5-bit port digital IO card in FMC form-factor. Each
single-bit port can be configured individually as input or output. The
I/Os on LEMO 00 connectors are TTL compatible. Commercially available.

The CUTE-WR-DP is the enhanced version of CUTE-WR with dual WR ports.
You can use it as the normal WR node with one SFP port.
CUTE-WR-DP can work in chain to support cascade topology.
In future, CUTE-WR-DP could support dualport redundancy function for
high reliable application.

FMC DIO 32CH LVDS is a universal 32-channel bi-directional LVDS card. It
uses a VHDCI connector compatible with standard SCSI cables. There is
also micro-HDMI connector on the front panel with I2C and some LVDS
signals so that standard HDMI cables can be used. Each channel may be
optionally AC-coupled (0R resistors need to be removed) and is
ESD-protected. All channels are terminated to 1.65V by two 50 Ohm
resistors. The direction of each channel is programmed via a serial
interface.
The VHDCI connector has also 3.3V supply and buffered I2C interface. The
direction of each channel is programmed via a serial interface.
